+// This is the file with the issue.  It has items within the boost::detail
+// namespace that referenced an unadorned "integer_traits".  This was meant to
+// refer to boost::integer_traits.  However, <boost/detail/numeric_traits.hpp>
+// defines a boost::detail::integer_traits.  If that header is #included before
+// this one, then b.d.integer_traits (rightfully) took priority, which lead to a
+// syntax error.
